Update CI workflow and ignore Claude Code files

Updates GitHub Actions workflow to use modern versions and removes manual
directory creation now handled by the upgraded API script.

Workflow changes:
- Upgrade to latest action versions (checkout@v6, setup-python@v5)
- Use Ruby 3.3 and Python 3.14 for current language versions
- Separate build and deploy jobs following GitHub Pages best practices
- Replace deprecated peaceiris/actions-gh-pages with actions/deploy-pages
- Remove manual mkdir as api.py now handles directory creation automatically
- Trigger on pull requests for validation before merge

Also adds .claude directory to .gitignore to exclude Claude Code
configuration files from version control.
